EXPLOIT

WebPageTest version 2.6 and earlier contains an arbitrary file upload vulnerability in the resultimage.php script. The application fails to validate or sanitize user-supplied input before saving uploaded files to a publicly accessible directory. This flaw allows remote attackers to upload and execute arbitrary PHP code, resulting in full remote code execution under the web server context.

• → Monitor for unauthenticated POST requests to resultimage.php, especially those uploading files with PHP extensions (.php, .php3, .phtml, etc.) to the web-accessible directory. ↗
• → Alert on web server execution of newly created PHP files in the WebPageTest results/upload directory, which may indicate successful exploitation and remote code execution. ↗
• → Flag any HTTP requests that result in PHP code execution originating from the web server process following a file upload to WebPageTest, as this indicates post-exploitation activity. ↗

• · Vulnerability is present in WebPageTest version 2.6 and earlier; verify the installed version before applying detection rules to avoid false positives on patched instances. ↗
• · The uploaded malicious file is placed in a publicly accessible web directory, meaning detection should also cover direct HTTP GET requests to newly uploaded files in that directory, not just the upload POST. ↗
